Supreme Court of Canada Hearings

B.F., a surgical nurse, has a child, E. B.F. and E.’s father are separated and, in 2019, were engaged in litigation about parenting rights. An interim ruling in that case in early June 2019 granted E.’s father supervised access, which B.F. resisted. At this time, B.F. was residing with her mother, I.F.On June 12, 2019, after the interim ruling, a neighbour found B.F., I.F., and E., then 19 months old, in B.F.’s home. All three were unconscious in B.F.’s bedroom; E. was in her crib. First responders found five empty insulin pens at the scene, each of which originally contained many times the normal adult dose. There were nine visible injection marks on E.’s body and evidence that E. had resisted the injections; no injection marks were visible on B.F. or I.F. The first responders also located a handwritten letter at the scene that they characterized as a suicide note. Due to the quantity of insulin injected into her system, E. suffered serious and permanent brain damage, as well as permanent damage to other organs. She was diagnosed with cerebral palsy and spasticity, and suffers from seizures. She requires constant medical care. B.F. and I.F. have since fully recovered. B.F. was arrested and charged with two counts of attempted murder by administering a noxious substance (a potentially lethal amount of insulin by injection), and two counts of aggravated assault.The jury convicted B.F. of the attempted murder of E. and I.F., and of the aggravated assault of E. The jury acquitted B.F. of the aggravated assault of I.F.B.F. appealed her conviction and sentence. The conviction appeal in relation to the attempted murder of E. was dismissed. The conviction appeal in relation to the attempted murder of I.F. was allowed and a new trial ordered.
